  • Abstract
  • Look Inside

The minimum visual acuity requirements for seamen has been set, officially, at 0.5 for offi-cers. Lower standards have been set for wor-kers aboard below the rank of officers.

In consideration of the actual nature of acti-vity and the current status of visual function in 188 normal and 373 sick seamen examined by the present authors, a proposal is made for a standard visual acuity requirements for sea-men as follows :

The officers aboard, i. e. captain, pilot, navi-gator and chief engineer, ought to have visual acuity of more than 0.8 in each eye.
